Recent releases

Release Notes: This version adds the ability to make aggregate relationships navigable through the new @navhas and @navcomposed relationships, makes UMLGraphDoc generation compatible with JDK 7, improves the documentation, and moves the project's source code repository hosting to GitHub.

Release Notes: This version creates clickable diagram elements in HTML content, makes the generation of diamond shapes compatible with GraphViz 2.27, and includes a fix to ensure that class images only appear once in the generated diagrams.

Release Notes: A new -dotexecutable option allows the explicit specification of dot's location. In addition, UMLGrpah now supports javadoc's -linkoffline option. Documentation generated with UMLGraph will correctly process non-ASCII characters, will correctly hide relations of hidden fields, and will use by default a logical font rather than a font file name for italics. In addition, UmlGraphDoc will now obey the options specified through @opt tags within Java files. Finally, sequence diagrams provide an option to specify whether objects are underlined or not.

Release Notes: This version corrects an exception when a
dependency to an unknown class is specified. It
also fixes a NullPointerException that occurred
when no global options are available. It also
corrects the case of the tools.jar filename in the
umlgraph shell script.

Release Notes: This version has active classes appearing with a double vertical border as required by UML2, two new class diagram options that control the node and rank separation of the nodes in generated diagram layout, support for showing a class's title as a tooltip in image files, and an option for generating Javascript-collapsible UML diagrams in Javadoc files.

Recent comments

I am using the UMLGraph jar directly and it is reporting a lot of problems of the kind:
package X does not exist
cannot find symbol symbol : Y
for files not included as part of the command.
Is there a way to ignore external packages/files (I am not really interested in UML for these anyway) or is there a way to add them as external dependencies?

UmlGraphDoc.runGraphviz() should return a boolean (false on exception) or an IOException in case of a error in "Runtime.getRuntime().exec()", because the calling methods (like generatePackageDiagrams()) do not interrupt in case of a exception. So UmlGraphDoc.runGraphviz() will always return 'true' and only a System.out message is printed.

Not sure how else to contact the project author, so I just wanted to report a bug in UMLGraph 5.2 - if you have a method in the Java source file which either returns a generic type, or uses a generic type as one of its parameters, then UMLGraph barfs on the output.
